(This looks to me more as a bug report than as a feature request.)
Hello. When you split an item at transients it’s a healthy thing to keep those transients untouched, not reduced in volume in any way.
From that point of view, the default crossfade action seems odd as it does quite the opposite — it leaves the tail unaffected (adds the fade-out right after it) and reduces the volume of the transient at hand.
Setting the fade length to the negative value simply doesn’t work.
So, if I split the items to quantize or otherwise rearrange them I'll have to deal with those added bits of audio at the end of every item — added there by the default action.
Now, there’s this action:
SWS/AW: Split selected items at edit cursor w/crossfade on left
which seems to do pretty close to what I need.
But why can’t it be assigned as a default crossfade action?
And why can’t a user have an option to crossfade items without overlapping — just a clear fade-out and a clear fade-in?
With the “Dynamic split items…” action it gets slightly more interesting.
Setting the Trailing pad to the negative value actually does work.
But in this case, there’s no fade-out, only the fade-in (with the “Fade pad” checkbox ticked).
And with the positive value (by default) we get both fade-in and fade-out and totally unneeded bits of audio kept or added:
And the “Dynamic split items…” action hasn't "noticed" which fade curve is selected in the Preferences.
